  • BOXED WARNING (What is this?)

    WARNING: CYTOKINE RELEASE SYNDROME

    Cytokine release syndrome (CRS), including serious or life-threatening reactions, can occur in patients receiving LUNSUMIO. Initiate treatment with the LUNSUMIO step-up dosing schedule to reduce the risk of CRS. Withhold LUNSUMIO until CRS resolves or permanently discontinue based on severity [see Dosage and Administration (2.1 and 2.4) and Warnings and Precautions (5.1)].

  • 1 INDICATIONS AND USAGE

    1.1 Follicular Lymphoma

    LUNSUMIO is indicated for the treatment of adult patients with relapsed or refractory follicular lymphoma after two or more lines of systemic therapy.

    This indication is approved under accelerated approval based on response rate [see Clinical Studies (14.1)]. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s).

  • 2 DOSAGE AND ADMINISTRATION

    2.1 Important Dosing Information

    • Administer LUNSUMIO to well-hydrated patients.
    • Premedicate before each dose in Cycle 1 and Cycle 2 [see Dosage and Administration (2.2)].
    • Administer only as an intravenous infusion through a dedicated infusion line. Do not use an in-line filter to administer LUNSUMIO. Drip chamber filters can be used to administer LUNSUMIO.
    • LUNSUMIO should only be administered by a qualified healthcare professional with appropriate medical support to manage severe reactions such as cytokine release syndrome and neurologic toxicity [see Warnings and Precautions (5.1 and 5.2)].

    2.2 Recommended Dosage

    The recommended dosage for LUNSUMIO is presented in Table 1.

    Administer for 8 cycles, unless patients experience unacceptable toxicity or disease progression.

    For patients who achieve a complete response, no further treatment beyond 8 cycles is required. For patients who achieve a partial response or have stable disease in response to treatment with LUNSUMIO after 8 cycles, an additional 9 cycles of treatment (17 cycles total) should be administered, unless a patient experiences unacceptable toxicity or disease progression.

    None.

  • 5 WARNINGS AND PRECAUTIONS

    5.1 Cytokine Release Syndrome

    LUNSUMIO can cause cytokine release syndrome (CRS), including serious or life-threatening reactions [see Adverse Reactions (6.1)].

    Cytokine release syndrome occurred in 39% of patients who received LUNSUMIO at the recommended dose in the clinical trial, with Grade 1 CRS occurring in 28%, Grade 2 in 15%, Grade 3 in 2%, and Grade 4 in 0.5% of patients. Recurrent CRS occurred in 11% of patients. Most patients experienced CRS following doses of 1 mg on Cycle 1 Day 1 (15%), 2 mg on Cycle 1 Day 8 (5%), and 60 mg on Cycle 1 Day 15 (33%). Five percent of patients experienced CRS after receiving 60 mg on Cycle 2 Day 1 with 1% of patients experiencing CRS following subsequent dosages of LUNSUMIO.

    The median time to onset of CRS from the start of administration in Cycle 1 Day 1 was 5 hours (range: 1 hour to 3 days), Cycle 1 Day 8 was 28 hours (range: 5 hours to 3 days), Cycle 1 Day 15 was 25 hours (range: 0.1 hours to 16 days), and Cycle 2 Day 1 was 46 hours (range: 12 hours to 3 days). The median duration of CRS was 3 days (range: 1 to 29 days).

    Clinical signs and symptoms of CRS included, but were not limited to, fever, chills, hypotension, tachycardia, hypoxia, and headache. Concurrent neurologic adverse reactions occurred in 6% of patients and included but were not limited to headache, confusional state, and anxiety.

    Initiate therapy according to LUNSUMIO step-up dosing schedule to reduce the risk of CRS [see Dosage and Administration (2.3)]. Administer pretreatment medications to reduce the risk of CRS, ensure adequate hydration, and monitor patients following administration of LUNSUMIO accordingly.

    At the first sign of CRS, immediately evaluate patients for hospitalization, manage per current practice guidelines and administer supportive care; withhold or permanently discontinue LUNSUMIO based on severity [see Dosage and Administration (2.4)].

    Patients who experience CRS (or other adverse reactions that impair consciousness) should be evaluated and advised not to drive and to refrain from operating heavy or potentially dangerous machinery until resolution.

    5.2 Neurologic Toxicity

    LUNSUMIO can cause serious neurologic toxicity, including Immune Effector Cell-Associated Neurotoxicity Syndrome (ICANS) [see Adverse Reactions (6.1)].

    Neurologic toxicity occurred in 39% of patients who received LUNSUMIO at the recommended dose in the clinical trial, with Grade 3 neurologic toxicity occurring in 3% of patients. The most frequent neurologic toxicities were headache (21%), peripheral neuropathy (13%), dizziness (11%), and mental status changes (6%, including confusional state, disturbance in attention, cognitive disorder, delirium, encephalopathy, and somnolence). ICANS was reported in 1% of patients (Grade 1: 0.5%, Grade 2: 0.5%) who received LUNSUMIO at the recommended dose in the clinical trial.

    Coadministration of LUNSUMIO with other products that cause dizziness or mental status changes may increase the risk of neurologic toxicity.

    Monitor patients for signs and symptoms of neurologic toxicity during treatment. At the first sign of neurologic toxicity, including ICANS, immediately evaluate the patient, consider neurology evaluation as appropriate, and provide supportive therapy based on severity; withhold or permanently discontinue LUNSUMIO based on severity and follow management recommendations [see Dosage and Administration (2.4)].

    Patients who experience neurologic toxicity such as tremors, dizziness, insomnia, severe neurotoxicity, or any other adverse reactions that impair consciousness should be evaluated, including potential neurology evaluation, and patients at increased risk should be advised not to drive and to refrain from operating heavy or potentially dangerous machinery until resolution.

    5.3 Infections

    LUNSUMIO can cause serious or fatal infections [see Adverse Reactions (6.1)].

    Among patients who received LUNSUMIO at the recommended dose in the clinical trial, serious infections, including opportunistic infections, occurred in 17%, with Grade 3 or 4 infections in 14%, and fatal infections in 0.9% of patients. The most common Grade 3 or greater infections were pneumonia, sepsis, and upper respiratory tract infection.

    Monitor patients for signs and symptoms of infection prior to and during treatment with LUNSUMIO and treat appropriately. LUNSUMIO should not be administered in the presence of active infection. Caution should be exercised when considering the use of LUNSUMIO in patients with a history of recurring or chronic infections (e.g., chronic, active Epstein-Barr Virus), with underlying conditions that may predispose to infections or who have had significant prior immunosuppressive treatment. Administer prophylactic antimicrobials according to guidelines.

    Withhold LUNSUMIO or consider permanent discontinuation of LUNSUMIO based on severity [see Dosage and Administration (2.4)].

    5.4 Cytopenias

    LUNSUMIO can cause serious or severe cytopenias, including neutropenia, anemia, and thrombocytopenia [see Adverse Reactions (6.1)].

    Among patients who received the recommended dosage in the clinical trial, Grade 3 or 4 decreased neutrophils occurred in 38%, decreased hemoglobin in 19%, and decreased platelets in 12% of patients. Grade 4 decreased neutrophils occurred in 19% and decreased platelets in 5% of patients. Febrile neutropenia occurred in 2%.

    Monitor complete blood counts throughout treatment. Based on the severity of cytopenias, temporarily withhold, or permanently discontinue LUNSUMIO. Consider prophylactic granulocyte colony-stimulating factor administration as applicable [see Dosage and Administration (2.4)].

    5.5 Tumor Flare

    LUNSUMIO can cause serious or severe tumor flare [see Adverse Reactions (6.1)].

    Among patients who received LUNSUMIO at the recommended dosage in the clinical trial, tumor flare occurred in 4% of patients. Manifestations included new or worsening pleural effusions, localized pain and swelling at the sites of lymphoma lesions, and tumor inflammation.

    Patients with bulky tumors or disease located in close proximity to airways or a vital organ should be monitored closely during initial therapy. Monitor for signs and symptoms of compression or obstruction due to mass effect secondary to tumor flare. If compression or obstruction develops, institute standard treatment of these complications.

    5.6 Embryo-Fetal Toxicity

    Based on its mechanism of action, LUNSUMIO may cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to the fetus. Advise females of reproductive potential to use effective contraception during treatment with LUNSUMIO and for 3 months after the last dose [see Use in Specific Populations (8.1, 8.3)].

  • 6 ADVERSE REACTIONS

    The following adverse reactions are described elsewhere in the labeling:

    6.1 Clinical Trials Experience

    Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

    The pooled safety population described in the WARNINGS AND PRECAUTIONS reflects exposure to LUNSUMIO as a single agent in GO29781 in 218 patients with hematologic malignancies in an open-label, multicenter, multi-cohort study. Patients received step-up doses of 1 mg on Cycle 1 Day 1 and 2 mg on Cycle 1 Day 8, followed by 60 mg on Cycle 1 Day 15, and 60 mg on Cycle 2 Day 1, then 30 mg every 3 weeks in subsequent cycles. A treatment cycle was 21 days. Among 218 patients who received LUNSUMIO, 52% were exposed for at least 8 cycles and 8% were exposed for 17 cycles.

    In this pooled safety population, the most common (≥ 20%) adverse reactions were cytokine release syndrome (39%), fatigue (36%), rash (34%), pyrexia (24%), and headache (21%). The most common Grade 3 to 4 laboratory abnormalities (≥ 10%) were decreased lymphocyte count (92%), decreased phosphate (41%), increased glucose (40%), decreased neutrophil count (38%), increased uric acid (15%), decreased white blood cell count (22%), decreased hemoglobin (19%), and decreased platelets (12%).

    Relapsed or Refractory Follicular Lymphoma

    GO29781

    The safety of LUNSUMIO was evaluated in GO29781, an open-label, multicenter, multi-cohort study which included a cohort of 90 patients with relapsed or refractory follicular lymphoma (FL) [see Clinical Studies (14)]. In this cohort, patients with relapsed or refractory FL were required to have received at least two prior lines of systemic therapy, including an anti-CD20 monoclonal antibody and an alkylating agent. Patients received step-up doses of 1 mg on Cycle 1 Day 1 and 2 mg on Cycle 1 Day 8, followed by 60 mg on Cycle 1 Day 15 and 60 mg on Cycle 2 Day 1, then 30 mg every 3 weeks in subsequent cycles. A treatment cycle was 21 days. The median number of cycles was 8 (range: 1 – 17). In the relapsed or refractory FL cohort, 77% were exposed for at least 8 cycles and 12% were exposed for 17 cycles.

    The median age of the patients who received LUNSUMIO in the relapsed or refractory FL cohort was 60 years (range: 29 to 90 years), 61% were male, 82% were White, 4% were Black or African American, 9% were Asian, and 8% were Hispanic or Latino.

    Serious adverse reactions occurred in 47% of patients who received LUNSUMIO. Serious adverse reactions in ≥ 2% of patients included cytokine release syndrome, infection (including urinary tract infection, sepsis, pneumonia, EBV viremia, and COVID-19), renal insufficiency, pyrexia, and tumor flare.

    Permanent discontinuation of LUNSUMIO due to an adverse reaction occurred in 3% of patients. Adverse reactions resulting in permanent discontinuation of LUNSUMIO included cytokine release syndrome and EBV viremia.

    Dosage interruptions of LUNSUMIO due to an adverse reaction occurred in 37% of patients. Adverse reactions which required dosage interruption in ≥ 5% of patients included neutropenia, infection, and cytokine release syndrome.

    Table 8 summarizes the adverse reactions in patients with relapsed or refractory FL in GO29781.

  • 7 DRUG INTERACTIONS

    Effect of LUNSUMIO on CYP450 Substrates

    LUNSUMIO causes release of cytokines [see Clinical Pharmacology (12.2)] that may suppress activity of CYP450 enzymes, resulting in increased exposure of CYP450 substrates. Increased exposure of CYP450 substrates is more likely to occur after the first dose of LUNSUMIO on Cycle 1 Day 1 and up to 14 days after the second 60 mg dose on Cycle 2 Day 1 and during and after CRS [see Warnings and Precautions (5.1)]. Monitor for toxicity or concentrations of drugs that are CYP450 substrates where minimal concentration changes may lead to serious adverse reactions. Consult the concomitant CYP450 substrate drug prescribing information for recommended dosage modification.

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Risk Summary

    Based on the mechanism of action, LUNSUMIO may cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1)]. There are no available data on the use of LUNSUMIO in pregnant women to evaluate for a drug-associated risk. No animal reproductive or developmental toxicity studies have been conducted with mosunetuzumab-axgb.

    Mosunetuzumab-axgb causes T-cell activation and cytokine release; immune activation may compromise pregnancy maintenance. In addition, based on expression of CD20 on B-cells and the finding of B-cell depletion in non-pregnant animals, mosunetuzumab-axgb can cause B-cell lymphocytopenia in infants exposed to mosunetuzumab-axgb in-utero. Human immunoglobulin G (IgG) is known to cross the placenta; therefore, LUNSUMIO has the potential to be transmitted from the mother to the developing fetus. Advise women of the potential risk to the fetus.

    In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% – 4% and 15% – 20%, respectively.

    8.2 Lactation

    Risk Summary

    There is no information regarding the presence of mosunetuzumab-axgb in human milk, the effect on the breastfed child, or milk production. Because human IgG is present in human milk, and there is potential for mosunetuzumab-axgb absorption leading to B-cell depletion, advise women not to breastfeed during treatment with LUNSUMIO and for 3 months after the last dose.

    8.3 Females and Males of Reproductive Potential

    LUNSUMIO may cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1)].

    Pregnancy Testing

    Verify pregnancy status in females of reproductive potential prior to initiating LUNSUMIO.

    Contraception

    Females

    Advise females of reproductive potential to use effective contraception during treatment with LUNSUMIO and for 3 months after the last dose.

    8.4 Pediatric Use

    The safety and efficacy of LUNSUMIO have not been established in pediatric patients.

    8.5 Geriatric Use

    Among the 90 patients with relapsed or refractory follicular lymphoma treated with LUNSUMIO, 33% were 65 years of age or older, and 8% were 75 years of age or older. There is an insufficient number of patients 65 years of age or older and 75 years of age or older to assess whether there are differences in safety or effectiveness in patients 65 years of age and older compared to younger adult patients.

  • 11 DESCRIPTION

    Mosunetuzumab-axgb is a bispecific CD20-directed CD3 T-cell engager. It is a humanized monoclonal anti-CD20xCD3 T-cell-dependent bispecific antibody of the immunoglobulin G1 (IgG1) isotype. Mosunetuzumab-axgb is produced in Chinese Hamster Ovary (CHO) cells by recombinant DNA technology. The approximate molecular weight is 146 kDa.

    LUNSUMIO (mosunetuzumab-axgb) injection is a sterile, preservative-free, colorless solution for intravenous use.

    Each single-dose vial contains a 1 mL solution of mosunetuzumab-axgb (1 mg), acetic acid (0.4 mg), histidine (1.6 mg), methionine (1.5 mg), polysorbate 20 (0.6 mg), sucrose (82.1 mg), and Water for Injection, USP. The pH is 5.8.

    Each single-dose vial contains a 30 mL solution of mosunetuzumab-axgb (30 mg), acetic acid (12.8 mg), histidine (46.6 mg), methionine (44.8 mg), polysorbate 20 (18 mg), sucrose (2,462.4 mg), and Water for Injection, USP. The pH is 5.8.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    Mosunetuzumab-axgb is a T-cell engaging bispecific antibody that binds to the CD3 receptor expressed on the surface of T-cells and CD20 expressed on the surface of lymphoma cells and some healthy B-lineage cells.

    In vitro, mosunetuzumab-axgb activated T-cells, caused the release of proinflammatory cytokines, and induced lysis of B-cells.

    12.2 Pharmacodynamics

    After administration of the recommended dosage of LUNSUMIO, peripheral B-cell counts decreased to undetectable levels (< 5 cells/microliter) in most patients (92%) by Cycle 2 Day 1 and the depletion was sustained at later cycles including at Cycle 4 and Cycle 8.

    LUNSUMIO caused hypogammaglobulinemia (defined as IgG levels < 500 mg/dL). Among 67 patients with baseline IgG levels ≥ 500 mg/dL, 40% had their IgG level decreased to < 500 mg/dL after administration of the recommended dosage of LUNSUMIO.

    Plasma concentrations of cytokines (IL-2, IL-6, IL-10, TNF-α, and IFN-γ) were measured, and transient elevation of cytokines were observed at doses of 0.4 mg and above. After administration of the recommended dosage of LUNSUMIO, the highest elevation of cytokines was observed within 24 hours after first dose on Cycle 1 Day 1 and after the first 60 mg dose on Cycle 1 Day 15. The elevated cytokine levels generally returned to baseline prior to the next infusion on Cycle 1 Day 8 and on Cycle 2 Day 1. Limited data is available in subsequent treatment cycles.

    12.3 Pharmacokinetics

    Mosunetuzumab-axgb PK exposure increased proportionally over a dose range from 0.2 mg to 60 mg (0.007 to 2 times the recommended treatment dosage). PK exposures are summarized for the recommended dosage of LUNSUMIO in Table 10 and Figure 1.

    Distribution

    The mean (CV%) volume of distribution of mosunetuzumab-axgb was 5.49 L (31%).

    Elimination

    The steady-state geometric mean (CV%) terminal elimination half-life of mosunetuzumab-axgb was 16.1 (17.3%) days. The geometric mean (CV%) clearance at baseline and at steady state are 1.08 L/day (63%) and 0.584 L/day (18%), respectively.

    Specific Populations

    There were no clinically significant differences in the pharmacokinetics of mosunetuzumab-axgb based on age (19 to 96 years), sex, race (Asian and Non-Asian), ethnicity (Hispanic/Latino and not Hispanic/Latino), mild or moderate renal impairment (estimated Creatinine clearance [CrCL] by Cockcroft-Gault formula: 30 to 89 mL/min), or mild hepatic impairment (total bilirubin less than or equal to upper limit of normal [ULN] with AST greater than ULN or total bilirubin greater than 1 to 1.5 times ULN with any AST). The effects of severe renal impairment (CrCL 15 to 29 mL/min) or moderate to severe hepatic impairment (total bilirubin greater than 1.5 times ULN with any AST) on the pharmacokinetics of mosunetuzumab-axgb are unknown.

    Drug Interaction Studies

    No clinical studies evaluating the drug interaction potential of mosunetuzumab-axgb have been conducted.

    12.6 Immunogenicity

    The observed incidence of anti-drug antibodies is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude meaningful comparisons of the incidence of anti-drug antibodies in the study described below with the incidence of anti-drug antibodies in other studies, including those of mosunetuzumab-axgb.

    During treatment in Study GO29781 (up to 12 months) [see Clinical Studies (14)], using an enzyme-linked immunosorbent assay (ELISA), no patients (N = 418) treated with LUNSUMIO developed anti-mosunetuzumab-axgb antibodies. Based on these data, the clinical relevance of anti-mosunetuzumab-axgb antibodies could not be assessed.

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    No carcinogenicity or genotoxicity studies have been conducted with mosunetuzumab-axgb.

    No dedicated studies have been conducted to evaluate the effects of mosunetuzumab-axgb on fertility. No adverse effects on either male or female reproductive organs were identified in a 26-week repeat dose chronic toxicity study in sexually mature cynomolgus monkeys.

  • 14 CLINICAL STUDIES

    The efficacy of LUNSUMIO was evaluated in an open-label, multicenter, multi-cohort study (GO29781, NCT02500407) in patients with relapsed or refractory follicular lymphoma (FL) who had received at least two prior therapies, including an anti-CD20 monoclonal antibody and an alkylating agent. The study excluded patients with active infections, history of autoimmune disease, prior allogeneic transplant, or any history of CNS lymphoma or CNS disorders.

    Patients received step-up doses of 1 mg on Cycle 1 Day 1 and 2 mg on Cycle 1 Day 8, followed by 60 mg on Cycle 1 Day 15, and 60 mg on Cycle 2 Day 1, then 30 mg every 3 weeks in subsequent cycles. A treatment cycle was 21 days. LUNSUMIO was administered for 8 cycles unless patients experienced progressive disease or unacceptable toxicity. After 8 cycles, patients with a complete response discontinued therapy; patients with a partial response or stable disease continued treatment up to 17 cycles, unless patients experienced progressive disease or unacceptable toxicity.

    Among the 90 patients with relapsed or refractory FL, the median age was 60 years (range: 29 to 90 years), 33% were 65 years of age or older, 61% were male, 82% were White, 9% were Asian, 4% were Black or African American, and 8% were Hispanic or Latino. A total of 77% of patients had Stage III-IV disease, 34% had bulky disease, and all patients had an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1. The median number of prior therapies was 3 (range: 2 to 10), with 38% receiving 2 prior therapies, 31% receiving 3 prior therapies, and 31% receiving more than 3 prior therapies.

    Seventy-nine percent of patients were refractory to prior anti-CD20 monoclonal antibody therapy, 53% were refractory to both anti-CD20 monoclonal antibody and alkylator therapy, 9% received prior rituximab plus lenalidomide therapy, 21% received prior autologous stem cell transplant, and 3% received prior CAR T therapy. Fifty-two percent of patients had progression of disease within 24 months of first systemic therapy.

    Efficacy was established on the basis of objective response rate (ORR) and duration of response (DOR) as assessed by an independent review facility according to standard criteria for NHL (Cheson 2007). The median follow-up for DOR was 14.9 months. The efficacy results are summarized in Table 11.

    (mosunetuzumab-axgb)
    injection, for intravenous infusion

    What is the most important information I should know about LUNSUMIO?
    LUNSUMIO may cause Cytokine Release Syndrome (CRS),     a serious side effect that is common during treatment with LUNSUMIO, and can also be severe or life-threatening.

    Get medical help right away if you develop any signs or symptoms of CRS at any time, including:

    • fever of 100.4°F (38°C) or higher
    • chills
    • low blood pressure
    • fast or irregular heartbeat
    • tiredness or weakness
    • difficulty breathing
    • headache
    • confusion
    • feeling anxious
    • dizziness or light-headedness
    • nausea
    • vomiting
    Due to the risk of CRS, you will receive LUNSUMIO on a "step-up dosing schedule".
    • The step-up dosing schedule is when you receive smaller "step-up" doses of LUNSUMIO on Day 1 and Day 8 of your first cycle of treatment.
    • You will receive a higher dose of LUNSUMIO on Day 15 of your first cycle of treatment.
    • If your dose of LUNSUMIO is delayed for any reason, you may need to repeat the "step-up dosing schedule."
    • Before each dose in Cycle 1 and Cycle 2, you will receive medicines to help reduce your risk of CRS.
    • See "How will I receive LUNSUMIO?" for more information about how you will receive LUNSUMIO.
    Your healthcare provider will check you for CRS during treatment with LUNSUMIO and may treat you in a hospital if you develop signs and symptoms of CRS. Your healthcare provider may temporarily stop or completely stop your treatment with LUNSUMIO, if you have severe side effects.
    See "What are the possible side effects of LUNSUMIO?" for more information about side effects.
    What is LUNSUMIO?
    LUNSUMIO is a prescription medicine used to treat adults with follicular lymphoma whose cancer has come back or did not respond to previous treatment, and who have already received two or more treatments for their cancer.
    It is not known if LUNSUMIO is safe and effective in children.
    Before receiving LUNSUMIO, tell your healthcare provider about all of your medical conditions, including if you:
    • have ever had an infusion reaction after receiving LUNSUMIO.
    • have an infection or have had an infection in the past which lasted a long time or keeps coming back.
    • have or had Epstein-Barr Virus.
    • are pregnant or plan to become pregnant. LUNSUMIO may harm your unborn baby. Tell your healthcare provider right away if you become pregnant or think you may be pregnant during treatment with LUNSUMIO.
      Females who are able to become pregnant:
      • your healthcare provider should do a pregnancy test before you start treatment with LUNSUMIO.
      • you should use an effective method of birth control during your treatment and for 3 months after the last dose of LUNSUMIO.
    • are breastfeeding or plan to breastfeed. It is not known if LUNSUMIO passes into your breast milk. Do not breastfeed during treatment and for 3 months after the last dose of LUNSUMIO.
    Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.

    How will I receive LUNSUMIO?

    • LUNSUMIO will be given to you by your healthcare provider by infusion through a needle placed in a vein (intravenous infusion).
    • After you complete the weekly "step-up dosing schedule" in Cycle 1, LUNSUMIO is given every 21 days.
    • After Cycle 1 and Cycle 2, your healthcare provider will decide if you need to continue to take other medicines to help reduce side effects from LUNSUMIO during future cycles.
    • Your healthcare provider will decide how many treatment cycles you will receive of LUNSUMIO.
    See "What is the most important information I should know about LUNSUMIO?" for more information about how you will receive LUNSUMIO.
    What should I avoid while receiving LUNSUMIO?
    Do not drive, operate heavy machinery, or do other dangerous activities if you develop dizziness, confusion, tremors, sleepiness, or any other symptoms that impair consciousness until your signs and symptoms go away. These may be signs and symptoms of CRS or neurologic problems.
    See "What is the most important information I should know about LUNSUMIO?" and "What are the possible side effects of LUNSUMIO?" for more information about signs and symptoms of CRS and neurologic problems.

    What are the possible side effects of LUNSUMIO?
    LUNSUMIO may cause serious side effects, including:
    See "What is the most important information I should know about LUNSUMIO?"

    • Neurologic problems. Your healthcare provider will check you for neurologic problems during treatment with LUNSUMIO. Your healthcare provider may also refer you to a healthcare provider who specializes in neurologic problems. Tell your healthcare provider right away if you develop any signs or symptoms of neurologic problems during or after treatment with LUNSUMIO, including:
    • headache
    • numbness and tingling of the arms, legs, hands, or feet
    • dizziness
    • confusion and disorientation
    • difficulty paying attention or understanding things
    • forgetting things or forgetting who or where you are
    • trouble speaking, reading, or writing
    • sleepiness or trouble sleeping
    • tremors
    • loss of consciousness
    • seizures
    • muscle problems or muscle weakness
    • loss of balance or trouble walking
    • Serious infections. LUNSUMIO can cause serious infections that may lead to death. Your healthcare provider will check you for signs and symptoms of infection before and during treatment. Tell your healthcare provider right away if you develop any signs or symptoms of infection during treatment with LUNSUMIO, including:
    • fever of 100.4°F (38°C) or higher
